A big thank you to @sktrip. The solution copied below worked. Thanks for your help.
I think I found a work around, goto forms, delete 199 Wrk Sheet. Save the file. Run the Check Errors again, you should not see any errors. Now go back to the forms section, in the top Select Open Forms, Select 199 Wrk Sheet (would be under 1020S forms). Reneter the information for the worksheet. Rerun the error and it should work.
